-------------------------------------
Summary: Table API client hangs when batch query returns an empty
result
Key: FLINK-40022
URL: https://issues.apache.org/jira/browse/FLINK-40022
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Reporter: Timo Theusner
`TableResult.await()` hangs for a bounded query that produces zero rows.
\{{await()}} blocks forever and \{{await(timeout)}} throws
\{{TimeoutException}}, even though the job finished successfully.
Can be reproduced:
{code:java}
TableEnvironment tEnv =
TableEnvironment.create(EnvironmentSettings.newInstance().inBatchMode().build());
TableResult result = tEnv.executeSql("SELECT * FROM (VALUES (1)) AS t(x) WHERE
x < 0");
result.await(); // hangs forever
{code}
